Hi all,
I''d like to have a macro like the following but preferably without
the 'eval' inside the assertion form:
(defmacro defcomponent [name co]
(assert (component? (eval co)) "Not a valid IComponent")
`(def ~name ~co))
If I don't use eval, everything works as long as I pass a var
in...However if I pass in something like (String. "jam") it is not
being evaluated and thus is a list not an object...and it will never
satisfy IComponent.
any thoughts?
thanks in advance :)
Jim
I could have phrased this better...One of my arguments has to NOT be
evaluated (name) but the other needs to be evaluated (co) so I can
assert whatever I want to assert on it...I cannot use 'defn' (it will
cause 'name' to be evaluated) so my only option is a macro that forces
eval on the second arg, yes?
Jim
